SPECIFICATION forming part of Letters Patent No. 260,349, dated June 27, 1882.l

Application tiled May 4, 1882. (No model.)

To all 'whom it may concern: spaces where the teeth are removed. Each Be itk known that I, HORACE WYMAN,ofthe cit-y and county ot' Worcester, State ot'Massa- Improvement in Mechanism for Converting Motion, of which the 'following description, in connection with the accompanying drawings, is a'speeilication. his my invention has for its object to move gear, as herein shown, contains nine separate teeth; or, what would be the same, each tenth tooth of the master-gear is'removed.

Thelever G, a lever of the first order, front end of which is to be moved at stated times ina longer or shorter are, rto thus reciprocate for a C2, it may be, or other device connected therewith, for a greater or less distance atone movement and in the same interval ot' fulorum on a pin, b, as herein shown, inserted through the forked upperf end, b', ot' a rod, b2, fitted loosely in and so as to rise and fall in a guiding-post, b3. The rear end of this lever has attached' to it a connecting rod, c, the lower end of which is fitted to a crank-pin, c', (shown in dotted lines, Fig. 1,) fixed tothe rear side of the disk c2,fast upon the Shaft c3, having A'its bearings iu the frame-work A. This shaft has splincd upon ita novel partially-tubular uplcx gear, c1, (see Fig. 2,) which is adapted to be reciprocated on the said shalt by means Ofa suitable lever, e, shaped as shown in Fig. 7, which will he pivoted on the framc-wor'kA, so that with its forked part embracing nularly-grooved part ot' the said termay be moved longitudinally on the shaft c, either by hand or by its connection with a lever or linger actnatedby what is known as a pattern-surface.

The gear (1(see Fig. 2) has two toothed parts, 3 -.t, 'each of which is shown in section in Figs. 9 and l0, wherein it will be seen that the toothed part 3 hasnearly one-half its teeth removed. leavingaseries of six teeth and an isolated tooth, 6, near one end ot' the said series, a'nd that the toothed part 4 has nearly one-lialt'ot' its teeth omitted, leaving a series ot' six teeth and an isolated tooth, 7. v

It will also be observed that the series ot therefor and my invention consists in a mechanical organinovel mechanical devices, forming part thereof', as will he hereinafter set forth and speciiied in the claims at the end of this specitication.

` Figure l represents in side elevation, parembodying my invention; Fig. 2, a top view thereof; Figs. 3 and 4, longitudinai'sectional details ot' two novel semi-rotating gears employed in the said train of mechanism; Fig. 5, in full lines,a\'crtical sectional detailot' Fig. 2 on the vdotted line the frame-work above the levers being removed; Fig. 6, a top view of Fig. 5, with the addition, in full lilies, of certain holding plates or devices, t-o be described 5 Fig. 7, a side elevation ot' one of my novel duplex semi-rotating gears, and theleverfor moving'the same longitudi- Daily, and the holder to operate upon the disk of the sha-ft with which the said gear is keyed; Fig. 8, a cross-section of one of the duplex gears on the dotted lines a, Fig. 7 5' Figs. 9` and 10, sections ot' the toothed portions 3 4 of one` of the'duplcx gears on dotted lines maar, Fig. 1 Fig. 1l, a. diagram illustrative ofthe different movements or positions o' the crank pins and levers.

The frame work to support the different working parte is marked A. The source ot' motion is thevtiiain shaft a, which is Vrotated -vcontlnnously.-`; This shaft has an arm, a2, provided with a pin, a?, which engages slots at, formed withinthemaste1gearB,the said arm, with relation to the shaft c, pin, and slots constituting a pin and starby the said gear c1. wheel coatrivance for moving themaster-gear` so as to place n intermittinggly., The peripheryof the masterof the teeth 132 of the master-gear B, the latter teeth with intervening will engage the said tooth and the series ot' greater or less distance a. rod,

an an-` gear, the lat- )Vixen the gear d is movedr the isola-ted tooth 6 in the path series of teeth at the periphery ofthe master-v 4' .teeth ot' the part 3 is diamctrically opposite six teeth at the rear of it, and rotate the said gear and the shaft c halt' a rotation, to move the crank-pin c' from one to its other extreme position, by which time the teeth of the inaster-wheel and toothed portion 3, extended but partially about gear d, will run out of mesh, and the gear d will remain idle with the crankpn c' at rest.

The crank-shafts c3 05j", arranged about the master-wheel B, have on them,respeetively, the disks c2 cf, which have portions ot' their peripheriescut away at two sides, as shown in Fig. l, and each disk has co-operating wi th it a. holder, 7i, which holds each disk with sufiieient force Ato preventit and the shaft with which it is connected from being rotated, except when the gear on the said shaft is in engagement with the teeth ofthe mastergear B. One of these holders or brakes h is shown fully in Fig. 7, where it will-be seen that the end ofthe brakeY lever is pivoted upon the lever e, which moves the duplex gears. Each holder or brake will' he held down by a spring, h". By moving the fulcrum-pin b of the lever C the latter may be raised and lowered without moving the crankpin c', and by moving the fulerum-pin and crank-pin c in opposite or in the same directions the throw of the outer end, 2, of the lever C may be more or less increased, and the end of the said lever may be moved into any one of the positions w 102103, &c.,.from any other of the said positions. rlhe pin I) of the lever C is extended through the central part of a lever, E, having slots c c at its opposite ends. rlhe slot creceivesablock,02, on acrankpin., c3, of the disk or plate c4, fast ou shaft e", the latter having on it a double gear, c6, which is constructed j ust the same as the gear d, hereinbeforc fully described. This gear e5, when moved horizontally on the shaft c" by a lever like the lever c, Fig. 7, will have its toothed parts thrown in'to engagement with the master-gear B, and will be rotated half a revolution to carry the crank-pin e2 from one toits other extreme position, when the said crank-pin and gear c6 will be left at rest until after the gear shall be/again' moved horizontally on itsshaft, as described of gear d, when the shaft and crank-pin will be again moved half a revolution. The crank-pin c3 will raise and lower the end ot' the lever E, with which it is connected. The slot c receives the block fon the crank-pin f2, carried by the disk f3, secured to the shaftf. (See Fig. 3.)

The shaft f4 has fixed to it a gear, g, having some of its teeth removed at dlametricallyopposte points, as shown in Figz, which is a section of Fig. 7 on the dotted line w. This gear is groovcd where its teeth are omitted, and receives in the said grooves the arms 10 12 ot' a hub, g, keyed to slide on the said shaft fi. The arms 10 12 of this hub have teeth 13 14 at different distances from the outer end of the hub g', the tooth 13 being 'nearer the end of the hub than the tooth 14, so that by sliding the said hub in one or the other direction the said teeth 13 14, which I call sliding teeth,7 may be placed in workin gposition with relation to the teeth ot' thc gear g, fixed cn'the shaft f4. If the toothM is moved into line with the teeth of the gear g, as in full lines, Figs. 3 and 7, it will be engaged by the master-wheel and be turned halt' a revolution, when, by reason ot' the toothless space diametrically opposite tooth 14, the teeth of the master-gear will run ont of mesh with the gear g, and the latter and the shaft f* and crankpin f2 will remain at rest until the hub g is shifted laterally by the lever 0asin dottedlines, Fig. 7, so as toearry the tooth14 away from the teeth of gear q and place tooth 13in line with its teeth, when theteeth of the master-gear willengage it, as the lirst tooth, and again turn the gear g and shaft f4 and crank-pin f2 half arcvolution. If both crank-pins f2 and e3 are simultaneously moved into their high points or their low points, both ends ol.' lever E will be raised or lowered equal distances and willliftor depress the fulerum-pin b of the lever C. If crank-pin f is moved into its high point and crank-pin c3 into its lowest position at the same time,the fulcrnm-pin b will notbe changed. The three crank-pins c, c, and f2, when all are operated together to move the fulcrum-pin Q and the outer end ot' the lever U in the same direction, will produce the maximum throw of the outer end ot' lever G, or from w to w, Fig. 1l.

cranks while all the others remain at rest will give the minimum movement to the outer end ot lever C, which is one-sixth that of the maximum,or from w to 102, so by turningthe crankpins to act all together, or in opposition, one or more to the other, the outer end of the lever U may be placed in any of the six positions, w', uit, Ste., Fig. 11.

To prevent the levers C and E from rocking or tipping, the sleeve lisiitted intotheguide b3.

In case the lever or its attached rod C2 has to carry a load, the weight of the load may be eounterbalaneed by the weights 40 41. (Shown in Fig. 5.)

1. Ahorzontally-sliding duplex gear, d, having two series ot' teeth, and teeth 6 7, removed one or more spaces therefrom to constitute toothless or blank spaces, as described, and shaft c", upon which the said gear is splined to be reciprocated, combined with the r'otating master-gear to operate the said duplex gear and shaft c;l half a revolution at a time, substantially as described.

2. The master-gearcombined with the crankshaft and a gear thereon having isolated teeth, or teeth removed one or more spaces from the main series of teeth of the latter gear, either of which isolated teeth may be placed in position to be engaged by the teeth ot' the mastergear to partially rotate the said crank-shaft, substantially as described.
